Company Secretary Ann Jones has resigned from the company.
Ann, who started working for the company in 1979, took over the running of the office, including responsibility for the accounts for the entire group, in 1986. She was appointed Company Secretary in 1991.
Ann will be taking a well-earned rest over the summer.
Managing Director Huw Jones said: “I want to thank my sister for all her hard work and dedication to the family business over the years.”
